A breast cancer vaccine developed at Washington University School of Medicine in St. Louis is safe in patients with metastatic breast cancer, results of an early clinical trial indicate. Preliminary evidence also suggests that the vaccine primed the patients' immune systems to attack tumor cells and helped slow the cancer's progression.

An experimental vaccine to prevent Ebola virus disease was well-tolerated and produced immune system responses in all 20 healthy adults who received it in a Phase 1 clinical trial conducted by researchers from the National Institutes of Health. The candidate vaccine, which was co-developed by the NIH's National Institute of Allergy and Infectious Diseases (NIAID) and GlaxoSmithKline (GSK), was tested at the NIH Clinical Center in Bethesda, Maryland.

The bacterium Helicobacter pylori is strongly associated with gastric ulcers and cancer. To combat the infection, researchers at University of California, San Diego School of Medicine and Jacobs School of Engineering developed LipoLLA, a therapeutic nanoparticle that contains linolenic acid, a component in vegetable oils.

While the turkey you eat on Thursday will bring your stomach happiness and could probably kick-start an afternoon nap, it may also save your life one day. That's because the biological machinery needed to produce a potentially life-saving antibiotic is found in turkeys. Looks like there is one more reason to be grateful this Thanksgiving.

A commonly prescribed muscle relaxant may be an effective treatment for a rare but devastating form of diabetes, researchers at Washington University School of Medicine in St. Louis report. The drug, dantrolene, prevents the destruction of insulin-producing beta cells both in animal models of Wolfram syndrome and in cell models derived from patients who have the illness.

Here is what we know: If people take medications prescribed to them, they usually get better. But only about half of all patients prescribed medication take it according to directions. Here is what we don't know: We don't know how to get patients to take their medications, despite many studies looking at the issue.

Chemists have developed a revolutionary new way to manufacture natural chemicals and used it to assemble a scarce anti-inflammatory drug with potential to treat cancer and malaria. The breakthrough could lead to new and cheaper ways to produce rare drugs in large quantities.
